"We had foundation repair done recently in bitter cold weather. Joe Autry, Larry Robinson, Dante' Gladden and William Lawrence worked continuously to get the job done before the snowstorm hit. These guys were unbelievable; they had to hand dig our property to get the job done. We are so impressed by their workmanship, work ethics and dedication to ensuring the job was done correctly."

"JES Foundation Repair (A Groundworks Company) proposed a solution for my basement wall reinforcement, and waterproofing. I accepted, and a date was set. They did not show up and it took 8 phone calls and 24 hours to find out that they weren't confident in their proposal. They increased the scope and added 50% to the cost. Stupidly, I signed again as time was wasting and I didn't want to start over with new vendors. JES completed the work while I was out of town. When I got back, there had been heavy rain and there was more water in my basement then I had ever experienced. I contacted my rep via text (impossible to get through by phone as he always was in "Training" when I called). His response was " That doesn't look good, I'll make some calls". I had to make the calls. JES sent several new employees out and they proposed additional work at ADDITIONAL cost. Unable to get satisfaction from mgmt. Had another foundation company finish the job. Do not use!"

"Great experience from the inspection of the issue, the estimate and the speed the job was scheduled and completed. Would (and already have) recommend to friends and clients (I'm a realtor). We had an engineer friend look at the solution Alex proposed for the job and he said this was the correct fix for the basement unlike a solution proposed my a different company. Thanks Alex!"

DiGiacomo Construction is family owned and operated. We've been in business in the Philadelphia and surrounding areas for over 20 years. We offer free estimates, veteran and senior citizen discounts and we are full licensed and insured. Quality, reliable workmanship at competitive prices are our top priority.

"Digiacomo construction was very professional in two jobs for us at our home. They demoed an old failing retaining wall and built a new wall to support a new garage. We also hired them to pour a new pad of concrete for the garage and a new pad for our back porch. They adjusted plans quickly and efficiently when an obstacle was encountered (our water line was where the original sonic tube would be) and the plan was updated to build around the line. I would generally not be able to be around to discuss plans so they would discuss work with my wife and we're always respectful to her when going over tasks and updates. We will hire them again in the future to complete work on our garden."

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "
